Lance Armstrong admits doping to win cycling titles

The American says Verbruggen approved the idea of backdating the prescription to help protect the image of the sport.

“We await proper considered outcomes from this investigation rather than rumour and accusation.”

In August 2012, Armstrong was stripped of his seven Tour de France titles and accused by the United States Anti-Doping Agency of the “most sophisticated, professionalised and successful doping programme sport has ever seen”.
